### Symfony version(s) affected6.3 and above### DescriptionDuring validation if we are using abstract base class with any Assert on property in it, and on child class we are overriding the property and Asserts current behaviour is enforcing the parent protected property Asserts. I.e.:```abstract class ParentClass{    public function __construct(        #[Assert\NotNull]        protected ?string $value        ) {    }}class Child extends ParentClass{    public function __construct(        #[Assert\Expression(expression: 'this.isValid() === true', message: 'value is invalid. ')]        #[Assert\Length(min: 11, max: 11, exactMessage: 'must be 11 digits long')]        #[Assert\NotBlank(message: 'value is required')]        #[Assert\Regex(pattern: '/^[0-9]+$/', message: 'Must contain digits only')]        protected ?string $value = null    ) {}}```### How to reproduceTo reproduce you will need validator, annotations and property access```composer require symfony/validator```example.php:```php<?php// composer require symfony/validatoruse Doctrine\Common\Annotations\AnnotationReader;use PHPUnit\Framework\TestCase;use Symfony\Component\Validator\ValidatorBuilder;// parent abstract classabstract class ParentClass{    public function __construct(        #[Assert\NotNull]        protected ?string $value        ) {    }}// example child classclass Child extends ParentClass{    public function __construct(        #[Assert\Expression(expression: 'this.isValid() === true', message: 'value is invalid. ')]        #[Assert\Length(min: 11, max: 11, exactMessage: 'must be 11 digits long')]        #[Assert\NotBlank(message: 'value is required')]        #[Assert\Regex(pattern: '/^[0-9]+$/', message: 'Must contain digits only')]        protected ?string $value = null    ) {}}// example test case class ExampleTest extends TestCase{    /**     *@dataProvider provideValues     */    public function testValidation(string $value, int $violationCount): void    {        $validatorBuilder = new ValidatorBuilder();        $validatorBuilder->enableAnnotationMapping()            ->setDoctrineAnnotationReader(new AnnotationReader());        $validator = $validatorBuilder->getValidator();        $child = new Child($value);        $this->assertEquals($violationCount, $validator->validate($child)->count());    }    /**     *@return array<int, string|int>[]     */    public function provideValues(): array    {        return [            ['07127669600', 0],            ['35424643507', 0],            ['11144477735', 0],            ['11144477734', 1],            ['11144477725', 1],            ['11111111111', 1],            ['55555555555', 1],            ['aaaaaaaaaaa', 1],            ['           ', 1],            ['071276696', 2],        ];    }}```### Possible SolutionFor the path in `\Symfony\Component\Validator\Mapping\ClassMetadata::mergeConstraints:349` handle not only private properties but also protectedin example:```php                if ($member instanceof MemberMetadata && (!$member->isProtected($this->name) && !$member->isPrivate($this->name))) {```
